It's easier and legal for the jew controlled media to just dig up something from your past, or just straight up make it up to character assassinate you by yelling it over every news station they control or retweeting it etc.

Or if your political party (or internet forum/website/following etc.) gets big enough, jew shills (the JIDF) will infiltrate it and cause it to start splintering like they attempt to do here and on any other websites that are against the jews or zionist state.

They can make things up. Even if it is exposed as a lie later it doesn't matter because the damage has already been done.

An example of how they do it is that some small blog will write some claim and have very poor proof and references to back it up. Then a bigger blog will quote it, then several blogs will quote it and each other until eventually the main stream will pick up on the story. By this point so many people are quoting each other as evidence (eg. CNN use FOX as their source and FOX uses CNN as their source) that nobody bothers to actually follow all the links and check the original place the claim came from.
By the time they retract the story it is too late and the damage has been done.

And there is no way you have lived your life like the Dalai Lama, they could find dirt on you with enough money and resources and spin it in a way to make you look bad. If you don't care, then congratulations you are the type of citizen they want, someone who wont challenge them. And if you don't challenge them and aren't a threat, they'll leave you alone to sit at home and watch TV. But if you're a threat, maybe an ex-girlfriend will come out one day who finally has found the confidence to say you raped her while you were together (remember Julian Assange).
Anyone who actually wants to make a difference has to worry about this once they make enough of an impact to be noticed.
